Maybe someone can help me to control the fan speed of my Dell Vostro 3450 with Ubuntu 11.10 X64 installed. When I open GNOME Image Viewer my fan speed is going up and spinning very fast.
I would like to know the reason why it does this.
Your CPU is pegged and it's heating up when you open Gnome Image Viewer. The fan speed is automatically adjusted by your BIOS via AMD Cool'n'Quiet™ or some other similar motherboard feature. Open the System Monitor to see how much CPU the app is using. EOG doesn't work for me in 11.10 because of a few bugs and I've since moved to Mirage.
